Application filed September 6,1924. Serial No. 736,292.

i To all whom t may concern.'

which the following is a specification.

This invention relates to pumps, and contemplates a structure whicheliminates the use of a pump rod,`the piston remaining stationary whilethe barrel of the pump is reciprocated, the invention being extremelysimple ,in construction and readily accessible for inspection or repairas the case may be.

The nature and advantages of the invention will be better understoodwhen the following detailed description is read in conv nection with theaccompanying drawings, the invention residing in the construction,combination and arrangementA of parts as claimed.

In the drawings forming part of this application, like numerals ofreference indicate similar parts in the several views, and wherein:

Figure 1 is a vertical sectional view through the structure forming thesubject matter of the present invention.

Figure 2 is a sectional view taken on line 2 2 of Figure 1,

Figure 3 is a sectional view on line 3 3 of Figure 1,

Figure 4 is a sectional view on line 4 4 of Figure 1, l

Figure 5 is a sectional view on line 5 5 of Figure 1.

Referring to the drawingsin detail 10 indicates the well casing providedwith a top or cover 11, the latter constituting a base to support ahollow standard made up of a plurality of packing glands and coupled asclearly illustrated in Figure 1. For instance, rising from the cover 11is a hollow boss 12 to which is secured the adjacent part 13 of apacking gland, the other component part of which is indicated at 14. Thepart 14 is fitted within the part 13, and interposed between these partsis the packing 15. Suitable fastening elements 16 are used to secure thepart 13 to the hollow boss. The part 13 has threaded or otherwisesuitably secured thereto a sleeve like member 17, the upper end of whichis connected with a coupling 18 having an outlet nipple 19 whichconstitutes the outlet for the pump. This coupling 18 has screwed orotherwise suitably secured thereto the adjacent part 19 of a packinggland, the other part of which is'indicated at`20. This part 2O ofcourse lits within the part 19, and interposed between saidl parts isthe packing 21 as clearlyv shown. The component parts 19 and 20 of thispacking gland are secured together by bolts or other suitable fasteningelements 22.

A tubing 23 of any suitable-dimension is passed through this hollowstandard composed of the elements just described', and entering the wellcasing 110, and is adapted to be reciprocated when use of the pump isdesired. The upper end of this tubing is closed by a headed plug 24, andrising from this plug is a hook like element 25 by means of which thetubing can be reciprocated for the purpose specified. Coupled as at 26to the lower end of the tubing 23 is a short length of pipe 27 which inturn is secured to a larger coupling sleeve 28, the lower end of which.receives a short length of pipe 29. The upper end of this pipe isnormally closed by a check valve 30 which is used in a manner and for apurpose to be presently described. The lower end of the pipe 29 iscoupled as at 31 to the upper end of thepump barrel 32, which barrel isprovided with a plurality of fluid inlet openings `33.

In this connection it will also be noted that the tubing 23 is providedwith a plurality of outlet openings 34. Secured to the lower end of thebarrel 33 is a coupling sleeve 35 which is slidably mounted on a shortrod 36, the upper end of which has secured thereto a stationary piston37 wholly positioned within the barrel 32. The lrod 36 may be of anysuitable length and has secured to the lower end thereof a weight 37which is adapted to rest or repose upon the bottom of the well, and thusmaintain the piston 37 stationary.

In practice, the piston is held stationary in the manner just stated andwhen the barrel 32 is moved upwardly from its lowermost position, asuction is createdin the barrel, so that when the openings 33 passbeyond the piston, the fluid is drawn into the barrel as will be readilyunderstood. When the barrel is moved downwardly, the piston forces thewater from the barrel through the short pipe 29 into the tubing 23, thecheck valve 30 closing after each operation to prevent back pressure, orre-' only very simple, but the pump can be conveniently and easilymanipulated in the manner and for the purpose specified, and byeliminating the use of a reciprocatory piston rod, the pump can beconveniently removed from the Well for inspection or repair as the casemay require.

Vhile it is believed that from the foregoing description, the nature andadvantages of the invention Will be readily apparent, I desire to haveit understood that I do not limit myself to what is herein shown anddescribed, and that such changes may be resorted to When desired as fallWithin the scope of What is claimed.

That I claim' is:

In combination, a Well casing, a cover therefor, a hollow' standardrising from the cover and including a plurality of'packing glands andcoupling members suitably secured together, a tubing arranged toreciprocate through said standard and Well casing, and having aplurality of outlet openings positioned at an appropriate point in itslength, a discharge nipple projecting from said standard, a pump barrelarranged beneath and in align with saidV tubing and having a pluralityof fluid Vinlet openings at an appropriate point in its length, meansfor coupling the said barrel With the lower end of said tubing, a checkvalve arranged above said barrel, a stationary piston arranged Withinthe barrel, a rod depending from said piston, and a Weight carried bythe lower end of the rod for holding said piston stationarywhile saidbar-- gel is reciprocated for the purpose speci- In testimony whereof Iaffix my signature.
